[Ecls-list] API prefix (ecl_) and ffi:c-lines

[Alexander Kjeldaas]

I don't see how your patch solves the problem you are faced with.  What do
you do the next time the name of an ecl_ function changes? You need to query
the version of the API as you say, and your patch does not provide a way to
do that.
